1640-1408 - Tweco Velocity Conductor Tube Insulator (Pack of 5)

Reliable Protection for Your Velocity MIG Gun

Keep your welding operations running without a hitch using the Tweco 1640-1408 Conductor Tube Insulator. If you are running a Tweco MIG gun equipped with Velocity consumables, you know the value of a smooth, stable arc. However, even the best equipment needs maintenance. The insulator on your conductor tube is the unsung hero that keeps the electricity flowing into the wire and not arcing out to the nozzle or your base metal where you don't want it.

Over time, heat and spatter can take their toll on gun insulators. A cracked or worn insulator can lead to frustrating arc instability, gas coverage issues, or even damage to your nozzle and contact tip holder. By replacing your old insulator with this genuine Tweco OEM part, you restore the factory-level safety and performance of your torch. The 1640-1408 is designed to slip perfectly onto Velocity conductor tubes, ensuring a snug fit that won't rattle or shift during use.

This package contains five insulators, making it a smart addition to your personal toolbox or shop supply cabinet. Don't let a small plastic part stop your production line. Swap out worn insulators during your regular torch maintenance routine to ensure every weld is as good as the first. Whether you are welding mild steel, stainless, or aluminum, maintaining the integrity of your gun's insulation is key to professional results and equipment longevity.
